NHOU Undercoating is a safe, affordable, extremely effective way to extend the life of your vehicle against damage caused by salt, liquid de-icing and winter driving conditions. 

NHOU Undercoating is self-healing and is constantly creeping, remaining active to continuously repel moisture and keep it away from the metal surface.

It is designed to penetrate the seams and crevices. It eliminates moisture. It actually terminates rust and corrosion in all metals, it protects vinyl and plastic surfaces from UV rays and improves the function of moving parts through lubrication.

NHOU® Oil Undercoating in Black not only protects—it instantly enhances the look of any metal surface. Unlike paint or traditional coatings that trap rust, our oil penetrates to the base metal, displaces moisture, and blocks oxygen. This self-healing formula stops oxidation at the source while leaving a clean, black finish.
